摘　　要： 目的:将目前增强型体外反搏(EECP)设备采集到的二进制数据文件转换为DICOM血液动力学波形文件。方法:在深入研究DICOM信息模型、DICOM波形文件结构、数据元素结构、嵌套数据集结构、波形IOD模块结构等的基础上,利用VisualC++.Net工具,运用C++面向对象编程思想,把数据元素、嵌套数据集、波形IOD及其操作服务抽象成类,再分别读取二进制数据文件的相关信息赋给波形类对应的数据成员,最后调用有关成员函数将其存储为DICOM波形文件。结果:设计出了基于DICOM标准的EECP血液动力学波形数据转换的应用程序。结论:DICOM标准的不断应用将涵盖所有医学成像和信号类设备,EECP数据的DICOM标准化转换,为其共享和充分利用提供了重要前提。 Objective： To convert the binary data files acquired from the Enhanced External Counterpulsation （EECP） devices into DICOM Hemodynamic waveform files. Methods： Based on the deep understanding of the DICOM Information model, the structure ofDICOM waveform file, Data Element, Nesting of Data Sets and the Waveform IOD Modules, using Visual C＋＋.Net as the development tool, with the object-oriented programming methodology, firstly, Data Element, Nesting of Data Sets and waveform IOD with their corresponding operations and services are respectively abstracted into classes. Then the values of attributes and waveform data are acquired by reading the binary data files and assigned to the corresponding data members of the waveform class. Finally, they are stored into a DICOM waveform file by invoking related functions. Results： An application has been achieved, which can convert EECP binary data files into DICOM hemodynamic waveform files successfully. Conclusions： With the development and application of DICOM, all medical imaging and waveform devices will support this standard. This system for conversion implements the DICOM normalization of EECP data, and provides the important condition for the comprehensive sharing and using of EECP data.
